Purpose: To demonstrate a modified surgical approach for horizontal ridge augmentation that allows for safe manipulation and predictable management of the buccal plate and avoids creation of a secondary surgical site. Materials and Methods: This pilot randomized controlled clinical trial included 24 patients who required horizontal alveolar ridge augmentation. Patients were assigned to one of the three groups: Group A was treated with the buccal plate repositioning (BPR) technique and grafted with silica calcium phosphate nanocomposite (SCPC) graft, group B was similarly managed and grafted using demineralized freeze-dried bone allograft (DFDBA), and group C was augmented using mandibular ramus autogenous bone block graft (ABBG). The primary outcome was the coronal crest width, which was measured at 6 months using CBCT. Results: The BPR technique resulted in horizontal augmentation with a mean of 4.30 ± 0.94 mm for group A, showing no significant difference from either group B (4.98 ± 1.13 mm) or group C (3.68 ± 0.27 mm). All augmented ridges allowed for successful implant placement with good primary stability. Conclusions: The BPR technique resulted in horizontal bone gain in extremely narrow alveolar ridges. It allowed for implant placement in a vascular cancellous bed protected by intact cortical plate. Different types of bone grafts, whether alloplast or allograft, resulted in successful augmentation comparable to that gained from autogenous block grafting. [ABSTRACT FROM AUTHOR] |
